1. O-ringing the head (or block). Is this a stock process or something done aftermarket for added performance? Is there any potential for problems if not done.

2. Head bolts. Is re-use just an unwise thing to do or something that you NEVER do? I'm having a fairly difficult time finding any at the local parts store. I'll going to check a machine shop nearby.

3. On the shortblock I bought recently some rocket scientist at the machine shop erroneously put the oil pickup tube mount bolt on the #2 main (instead of the #5 - or vice versa). Should I fix this myself or just try mounting the pickup tube on the #5 using the main cap bolt?

4. The only torque wrench I can find locally in 3/8" has its measurements in inch/lbs instead of ft/lbs. I've seen this in 2 different stores. I would guess that I could divide the reading by 12 to get the actual ft/lb. value. Is this correct?

Thanks!
